VFD Braking Torque [Archive] The Home Shop Machinist

I bought another braking resistor module in Ebay, and am in the process of swapping braking resistors on my mill and lathe. In my VFD manual, it has a table of braking resistor values for and 150% braking torque. Is there any reason I wouldn''t want to size the braking resistor for 150% torque? This is for a VFD installed on a 2 HP manual lathe (Clausing 5914).
